I cannot repro the error with Linaro GCC 4.9-2014.

I cannot repro the error with Linaro GCC 4.9-2014. This does look like something toolstack-specific: I installed gcc version 4.8.3 20140401 (prerelease) (crosstool-NG linaro-1.13.1-4.8-2014.04 - Linaro GCC 4.8-2014.04) from the link you provided above and it built without problems. -boris

After commit 8c058b0b9c34 ("x86/irq: Probe for PIC presence before allocating descs for legacy IRQs") early_irq_init() will no longer preallocate descriptors for legacy interrupts if PIC does not exist, which is the case for Xen PV guests. Therefore we may need to allocate those descriptors ourselves.
